.@helius got rejected fifty times before the first yes.

“It can’t just be adding a feature or a new button to an existing thing. It has to be something that people fundamentally don’t agree on today. Peter Thiel’s question, what truth do you believe in that nobody else believes in?”

“With Helius, I got rejected, I don’t know, 50 times or something before I got my first yes.”

“Every rejection just fired me up more to be like, you’re just stupid. And I will make more money than you and prove you’re wrong.”

I'm hiring a Sr. PM

scalable crypto has only existed for 2-3 years

there remains tremendous opportunity, invention, & glory for those who think about product from first principles

at Helius, you'll get a huge platform of products & users to build from

come work with me

“Crypto itself has existed since Bitcoin, technically speaking, which has been over a decade. However, programmable blockchains that scale, that are actually usable, have really only existed for maybe three years max.”

“People point to AI, but most people seem to not understand that AI has been around for over 50 years. People have been trying to work on AI since Alan Turing, since before computers even existed.”

“We’re only about two to three years into what’s possible on-chain.”

merts vibe slop explorer is pretty good these days

[Helius @Helius]

Only care about one wallet and one token?

Combine it with the tokenAccounts filter

Works in historical replay too so you can backfill 24 hrs of token activity

[Helius @Helius]

Your token feed shouldn’t miss transfers

Normal SPL transfers never put the mint in the list of account keys, so gRPC accountInclude filters never match it

LaserStream's new matchMints flag matches pre/post balances to fix this

Kyle built Gatekeeper, our edge gateway, and has been instrumental in shaping how we scale our network architecture to serve the Solana ecosystem

Check out his conversation with @nocircuit

[Solana Foundation @SolanaFndn]

New episode of The Stack with @nocircuit

@flkrs from @Helius shares how years of internet-scale networking work shaped the way he thinks about Solana and why low latency, edge architecture and reliability matter so much for the “Internet of Finance.” 

Listen to the episode 👇

[Stonk @LaunchOnSF]

Mert allocated everything to the network and nothing to the hairline, and for that, we're thankful.

You can now launch coins paired with solana:he1iusmfkpAdwvxLNGV8Y1iSbj4rUy6yMhEA3fotn9A, Helius’ liquid staking token, on StonkFun.

[Helius @Helius]

BAM Preconfirmations are now automatically included in Helius Preconfs, adding an additional 34% of network coverage

Stream transactions the instant a validator commits to executing them (the earliest onchain signal) with preconfSubscribe

Get started: https://t.co/8g9X0avmEK

[Jito @jito]

BAM Preconfirmations are now live via @Helius and @triton_one

Get access to the lowest latency data stream from validators running BAM-compatible clients; covering over 34% of network stake

[Solana Developers @solana_devs]

Great guide to Transaction v1.

[Helius @Helius]

@__lostin__ yes

[Impermanent Gains @__lostin__]

3.3x larger transactions are coming to Solana this week!

Transaction v1 is almost here

We wrote a developer guide to Solana’s transaction formats: legacy, v0, and the new v1 standard

[nick | helius.dev @nick_pennie]

today we completed the final clickhouse -> rocksdb migration for our historical data APIs

archival v3 is now live everywhere!!

performance is absolutely insane: p95 under 30ms (minus network) for all methods. getBlock shown below

enjoy

[nick | helius.dev @nick_pennie]

4 years ago, we were new to Solana and didn't have any funding. solana data wasn't human-readable. reading transactions required bespoke parsing and deep domain knowledge. we launched our first product, enriched transactions, to solve that problem. it was built using typescript + lambdas, funded my personal credit card.

it was a hit. we instantly got PMF. raised a seed round.

then market demand pivoted us downstream towards core infrastructure: RPCs, streaming, and validators.

today, we're going back to where we started: human-readable transactions. except now it's different. we learned from our mistakes and built it on top of foundational products like archival and laserstream.

parsed events core design principles:

1. instruction-level parsing (e.g. embedded swaps are parsed the exact same as regular swaps)
2. historical IDL parsing (e.g. parsers are aware of program updates & schema changes)
3. canonical data (e.g. parsers only use official sources such as on-chain IDLs)

Both are live in open beta and available on all paid plans

To get started, grab an API key from your Helius dashboard, and follow one of the quickstart guides on our docs

If you've ever tried to read a Solana transaction, you know the pain: it's a wall of base64 and addresses with no names

What happened? Who swapped what? You end up decoding it yourself

Not anymore

Introducing Parsed Streams and the Parsed Events API

Now in open beta

[Helius @Helius]

Want to look things up instead?

The Parsed Events API does the same decoding on demand over REST:

- give it a transaction signature → get it back decoded
- give it a wallet address → get its whole history decoded

All via one POST request
